Indian Stock Market Overview

NSE has around 1500 shares listed with a total market capitalization of around Rs 9,21,500 crore (Rs 9215-bln). The BSE has over 6000 stocks listed and has a market capitalization of around Rs 9,68,000 crore (Rs 9680-bln). Most key stocks are traded on both the exchanges and hence the investor could buy them on either exchange. Both exchanges have a different settlement cycle, which allows investors to shift their positions on the bourses.
The primary index of BSE is BSE Sensex comprising 30 stocks. NSE has the S&P NSE 50 Index (Nifty) which consists of fifty stocks. The BSE Sensex is the older and more widely followed index. Both these indices are calculated on the basis of market capitalization and contain the heavily traded shares from key sectors. The markets are closed on Saturdays and Sundays. Both the exchanges have switched over from the open outcry trading system to a fully automated computerized mode of trading known as BOLT (BSE On Line Trading) and NEAT (National Exchange Automated Trading) System. It facilitates more efficient processing, automatic order matching, faster execution of trades and transparency.
The scrips traded on the BSE have been classified into 'A', 'B1', 'B2', 'C', 'F' and 'Z' groups. The 'A' group shares represent those, which are in the carry forward system (Badla). The 'F' group represents the debt market (fixed income securities) segment. The 'Z' group scrips are the blacklisted companies. The 'C' group covers the odd lot securities in 'A', 'B1' & 'B2' groups and Rights renunciations.
